Value does NOT work cannot be converted to a value

Has anyone seen this error before, or know how to cure it. The error does not feature as a formula error - moreover it features as a Runtime error but doesn't stop the run execution.

The datacard corresponds to a SharePoint column that has been formatted as single line text, but is also displaying a number. The number is formatted in Power Apps to report a percentage or a some free text. I have tested it by typing the words " Does NOT work". The text patches through to SharePoint, but throws the error as reported. I was also hoping to display numbers as % if anyone knows how to do that in SharePoint (for a text column)

Hi @EddieE ,

You didn't specify whether your code is applicable for data formatted as numbers or single line text.

As Single line text, it only works for numeric values, while losing the "%" sign in the control.
It will not permit free text.

I think the issue is that you are trying to convert Text to a Value in your formula, eg

Value( "Does NOT Work") creates the error

To fix, you just need another condition inside your If() to cover this situation, try this

If( // condition 1 IsBlank(Parent.Default), Blank(), // condition 2 IsError( Value(Parent.Default) ), Parent.Default, // else condition Text( Value(Parent.Default) * 100, "#%" ) )

Also, to Patch the Blank(), make sure you have formula-level error management on in the Settings, ie

Re: Value does NOT work cannot be converted to a value

Hi @EddieE,
Thanks for dropping by and taking a look. Darn thing is giving me some grief 😕
My goal is to give the user the option to enter data either as text or a number formatted as a percentage. Originally I had the SharePoint list column uploaded as number formatted to %, but this didn't give the option to add free text I added an additional column to the list as single line text and gave the corresponding app control the following code in the default property.
If( IsBlank(Parent.Default), "", Text( Value(Parent.Default) * 100, "#%" ) )
That permits to patch a percentage value back to the SP List. If I then attempt to patch any free text back to the list, I get an initial error message saying there is a conflict with the server to patch that specific comment back. However, if I refresh the app, it permits me to patch it back, but not without a Runtime error.

@Anonymous - what is the actual field type of the SharePoint column? It is not clear from your description whether it is single line text or number.

If it is a number, that error should be expected because it looks as if you're trying to Patch Text values into a Number column.

Can you show the full error message?

Also, the DataCard setup would be helpful as well, eg Default property, any other properties that may affect this and the Update property of the DataCard
